The Best eSIM for Travel (2025): An Ultimate Guide

It used to be hard to stay in touch. In every new country, I would buy a real SIM card. This meant I had to change my UK SIM card, which would mean losing access to my normal phone number. This made it hard to do banking in other countries. The texts that were supposed to verify important things never came.

Thank goodness those days are over. I can now put an eSIM on my phone. It goes straight to my device. My physical SIM and eSIM work together perfectly. For any traveller, this technology is a game-changer. I can use all of my internet apps from anywhere. Google Maps always helps me find my way. My phone also turns into a personal hotspot (unless I can’t read maps!). This lets me work from any place. I can even watch a lot of my favourite Netflix shows on a long bus ride. But I have learnt one big thing. There are differences between eSIMs. Some are better than others. This is why I made this guide. I want to tell you about the best eSIMs for people who travel. This guide is for you. If you’re going on a short trip to the city. Or a long trip on a cruise. Or maybe even need to use the internet in the air. You can get an eSIM. Let’s look for the best one to keep you connected.

What is an eSIM? And why do you need one right away

Let’s get started with the basics. You might be wondering, “What is an eSIM?” The answer is easy. An eSIM is a SIM card that works electronically. It’s a small chip that is already inside your phone. You don’t have to put in a physical card. You can buy a data plan online. After that, the eSIM profile downloads to your phone. That’s all there is to it.

The Best Reasons to Use an eSIM When Travelling

• Keep Your Home Number: You can keep your main SIM card active. This is great for getting calls and texts at home. You can also get codes that prove your identity for banking.
• Instant Connectivity: You can buy and set up your eSIM before you even leave your house.
• Very Flexible: You can keep more than one eSIM profile on your phone. Going to a different country? Just change your eSIM profile. It’s easy.
• Better for the Environment: No plastic cards. No wrapping. An eSIM is a small but good thing for the world.

The Best eSIM for Travelling Abroad in 2025: My Top Picks

I’ve tried out a lot of different providers. These are the companies I trust after many trips. They are dependable, have great customer service, and are a great deal.

1. Airalo: Best for Options and Flexibility

For most of my trips, I use Airalo. I use it all the time. My review of Airalo is mostly good. I think it’s the most flexible Airalo eSIM provider out there.

What I like about Airalo:

• Global Coverage: Airalo has plans for more than 200 countries and regions, so it has a lot of coverage. You can get a local eSIM for just one country. You could also get a plan for Europe, Asia, or North America. They even have plans for long-term travel around the world.
• Pay-As-You-Go: You only pay for the data you need. Plans start at just 1GB for 7 days. This is great for short trips. You are never forced to sign up for a big, expensive plan.
• Easy-to-Use App: The Airalo app is great because it’s so easy to use. You can buy plans, install them, and add more data right from the app. It’s very easy to use.
• Reliable Networks: Airalo works with big local network providers. This means that most of the time, you can get strong, fast connections no matter where you are. A lot of online reviews of Airalo agree with this.

Best for: People who are travelling for a short time, backpackers who are moving between countries, and anyone who wants the most freedom.

2. Holafly: Best for Data Without Limits

There are times when you just need unlimited data. You don’t want to have to worry about running out. This is where Holafly shines. The Holafly eSIM is great for people who use a lot of data.

Why I like Holafly:

• Truly Unlimited Data: Holafly has unlimited data plans for a lot of popular places. This is a dream come true for people who work from home or travel a lot. You can browse, upload, and stream without any problems.
• Simple Choices: Holafly’s plans are based on how long you need them, not how much data you need. You can choose a plan that lasts for 5, 10, 15, or more days. This makes it very easy to pick a plan.
• Great Customer Service: They are available 24/7 on WhatsApp to help you. They are quick and useful.
• Phone Numbers Included in Some Areas: In Europe, Holafly now includes a European phone number with their plans. This lets you make and get calls, which is a big plus.

Best for: Digital nomads, people who work from home, content creators, and anyone who wants to know they have unlimited data.

3. Nomad: A Tough Competitor All Around

Nomad is another great option for eSIMs. The Nomad eSIM service is a lot like Airalo. It has a great mix of price, performance, and ease of use. Before I buy a plan, I always look at Nomad’s prices.

Why I like Nomad:

• Competitive Pricing: For some countries or data packages, Nomad eSIM plans are cheaper than Airalo plans. It always helps to compare.
• Good Regional Plans: Nomad also has a good range of regional plans. Their plans for the Asia-Pacific region are especially good deals.
• SMS Plans Available: One thing that makes Nomad different is that some of its plans let you send and receive SMS messages. This can be very helpful.
• Clean Interface: The Nomad website and app have a clean interface that is easy to use. It’s easy to buy and set up a plan.

Best for: Travellers who want to compare options to find the best deal without spending too much.

4. Vodafone eSIM: For People Who Trust Big Brands

You might like a name you know better. If you’re already a Vodafone customer, an eSIM might be a good choice.

Why you might want to think about a Vodafone eSIM:

• Trusted Network: You are connecting directly to a large global network. This can help you feel better.
• Easy Add-on: If you’re a Vodafone customer, you might be able to easily add a travel plan to your account.
• Roaming Packages: They have special roaming packages that can be turned on with an eSIM.

Best for: People who already have service with a major carrier or travellers who feel better with a well-known brand.

How to Pick the Best eSIM for Your Trip

It depends on how you like to travel and what the best eSIM is for you. These are the most important things to think about.

• Your Destination: Are you going to just one country? It’s best to get a local eSIM. Are you travelling through Southeast Asia with a backpack? A regional eSIM is easier to use.
• Length of Your Trip: A 3GB plan might be just right for a weekend trip. If you’re going to be gone for a month, you’ll need a bigger data package or an unlimited plan.
• Your Data Needs: How much data do you use? A small plan is fine if you only use maps and browse the web. You need more data if you work online, watch videos, or upload pictures. Think about getting an unlimited plan from a company like Holafly.
• Your Budget: Look at how much different providers, like Airalo and Nomad, charge. You can save money by doing some research.

Answers to Your Big eSIM Questions (FAQ)

Here are some easy-to-understand answers to the most common questions.

How to Install and Activate Your eSIM in a Few Easy Steps

It might sound technical to talk about an electronic SIM card. But the process is very easy. I’ll show you exactly what to do. This is how you can go from buying to browsing in just a few minutes.

Step 1: Before You Go

Getting ready is important. While you’re still connected to your home Wi-Fi, do these easy things.

• Check Phone Compatibility: First, make sure your phone can use an eSIM. Most phones made after 2019 do.
• Choose and Buy Your Plan: Go to a provider’s website like Airalo, Holafly, or Nomad.
• Have Your QR Code Ready: After you pay, the provider will email you a QR code. Some, like Airalo, let you install directly from their app. Keep this email or a screenshot of the QR code handy.

Step 2: The Installation Process (On Wi-Fi)

You must be connected to Wi-Fi to install your eSIM. Do this at home, at the airport, or in your hotel.

On an iPhone:

1. Tap “Add eSIM” or “Add Cellular Plan”.
2. Choose “Use QR Code”.
3. Scan the QR code from your provider.
4. Follow the on-screen prompts. Label your new eSIM something clear, like “Travel eSIM” or “Spain Data”. This makes it easy to manage.

On an Android Phone (Samsung/Google):

1. Go to Settings > Network & Internet.
2. Select “Download a SIM instead?” or “Add eSIM”.
3. Scan your QR code.
4. Follow the prompts to complete the installation.

Important: Do NOT activate the eSIM for data roaming until you arrive at your destination. Just install it.

Step 3: When You Arrive at Your Destination

This is the magic moment. The second your plane lands, you can get online.

1. Go back to your phone’s cellular settings.
2. Turn OFF your primary (home) SIM for data. This prevents expensive roaming charges.
3. Turn ON your new travel eSIM.
4. Enable “Data Roaming” for the travel eSIM only. This is required for it to connect to the local network.
5. Within a minute or two, your phone will connect to the local network. You’ll see a new signal bar. You are now online!

In the end, the time when you had to fumble with small plastic SIM cards and lose your home number is over. eSIMs have changed the way people connect while traveling.
